There has been no clear evidence to discriminate the nature of hearing impairment of idiopathic sudden deafness from acute hearing loss in patients with dialysis for renal failure, and treatment has never been established.<BR>In this report, five cases of hearing loss in the patients with dialysis for renal failure are presented. The patients had various renal diseases and receiving dialysis ranged from six months to eight years. Their hearing loss developed acutely and severity was from moderate to high. Two cases had vertigo. Steroids and vasodilators were used in four cases, but no severe complications were seen in their renal function. In three cases without vertigo hearing improvement was satisfactory but two cases with vertigo resulted in poor recovery. Therefore, vertigo might be a risk factor in hearing recovery as similar as in idiopathic sudden deafness.<BR>One case had no steroids treatment due to renal function and old age. She, however, showed good hearing recovery. Steroids might be not definitively necessary in the treatment of sensorineural hearing loss. If deafness is severe and recovery is delayed, steroids might be used safely with support of nephrologists.
